Question

the product of 2 expressions is x^5+x^3+x. if one of them is x^2+x+1 . find the other ​

Answer 1

Answer:

${x}^{3} ( {x}^{2} + x + 1) - {x}^{2} ( {x}^{2} + x + 1) \\ + 2x( {x}^{2} + x + 1) -1 ( {x}^{2} + x + 1) \\ \\ = ( {x}^{3} - {x}^{2} + 2x - 1)( {x}^{2} + x + 1)$

Step-by-step explanation:

First method is you can divide .

Other is right the x^2+x+1 in bracket , now in your expression there is a x^5 so multiply it by x^3 . Now there will be a x^4 too when you will open bracket but there isn't in your expression so multiply it by -1 . Again repeat process
